Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind, according to a new study from the University of Surrey.
Even without subsidies, renewables remain the lowest-cost new power sources for the 10th straight year . Fossil Fuels Lag in Cost: Coal power runs about $71–$173 per MWh, and natural gas $48–$109, far higher than wind or solar . The cheapest fossil generation (coal) is nearly double the average cost of utility-scale solar .
In 2024, solar photovoltaics (PV) were, on average, 41% cheaper than the lowest-cost fossil fuel alternatives, while onshore wind projects were 53% cheaper. Onshore wind remained the most affordable source of new renewable electricity at USD 0.034/kWh, followed by solar PV at USD 0.043/kWh.
The rise of wind and solar as the cheapest energy sources is no accident – it’s the result of decades of innovation, economies of scale, and learning-by-doing that have slashed the costs of renewable technology. Key trends and drivers include:
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
